To all "whom it may concern Be it known that We, Bonnier B. CAVERLY andALFRED B. BELL, citizens of the United States, residing at Philadelphia,in the county of Philadelphia and State of Exsylvania. have inventedcertain new and ful Improvements in Gas-Ranges, nsieh the following is aspecification.

)ur invention relates to gas ranges particularly to constructionscomprisirw .c

rious units which can be removably con nected together and so arrangedthat various types of range may be provided without the use ofadditional parts, or with the addition of only a few parts. Thus ourinvention may provide a sheet-metal gas range of the low cabinet typecomprising uni s which are interchangeable so that the construction maybe made either What is termed right hand range or a left hand rangewithout additional parts, and which, by a few changes in the arrangementof the gas supply pipe, and the substitution of four short legs in placeof the four long removable legs which are provided with the lov. cabinettype of range, may be made into a double oven type of range, the partsleft over being adapted to form a table if desired by the addition ofingly the provision of .eflicient, strong and comparative y inexpensiveconstructions of the character referred to, 7

Under various conditions. it has heretofore been necessary for merchantsto carry in stockvarious types of gas ranges. in accordance with ourinvention, a merchant may be provided ith one range which, by a simplerearrangement of the parts, may be converted into any one of three ormore types. Our invention also enables a householder to place a rangeinadifferent loco tion from that originally iru'rended. this becomesdesirable because of decrease in the space to be occupied by the range,or if the space is changled because of alterations. or

piping being sui ibly-srren for other reasons a, different typeof rangeis found to be preferubie to the one originally installed. ese variousconditions by our invention Without for t is labor necessary to sned atthe place of instaln may be briefly described as comprising base-framesecured to four sheet-metal legs a baking and a broiling oven arrangedone above the other in a uni tary reinforced sheet-metal construction, asheet-metal Warming oven unit and 2. burneroox unit. together with asplash. back and top shelf and other n cessary or desirable parts. T hedouble oven unit may be bolted in position Within the left hand end ofthe base-frame with the Warming oven and burner-ho); above the samesimilarly secured in place within the right hand end of thebiiSQ-fl'fililfi, the connections being suitably arranged and the splashhack and top shelf, if desired, being secured in place.

It is provided with a topsheet 52 formed from a sheet of metal and having flanges 53 turneddownward around three sides and having its front edge offset or bentdownwardly slightly as shown at 5%, to permit it to slip under theflange of the oven front. The oven body 55 is formed of sheet metalpressed into a three sided inclosure forming the two sides and back 55of the oven. To this body is electric welded or bolted the top 52 andalso the oven front 56 which is a frame having flanges turned inwardaround the outside edges, opening for doors with 'oiisets -to locate-thesame, and flanges 57 turned inward' ,1 around these openings. Holes are,pierced for the burners and gas rail support posts and for observationof burners. The oven top is provided with a flue hole at the back, asshown in Fig. 4 at 52, the flue collar 109, later referred to, be-

ing mounted over this hole, as shown in Figs. 4: and-9i To this ovenfront and body is electric Welded 0r bolted an angle iron base-frame 58similar to the angle iron baseframes previously describedas secured tothe bottoms of the warming oven unit and the burner-box unit. The ovenunit may be secured in position at either end of baseframe 1 by means ofbolts of screws 13 extending through the flanges of angles 11 on thelegs, the vertical flanges oi base-frame 1 and the bottom angle frame 58of the oven unit. This oven unit is provided with various liningmembers. A top lining 59 is provided with upwardly directed flanges suchas is shown at 60, thereby forming an air space in the top of the oven.This is provided with holes 59 at the front to permit cooking? vaporsand air to escape by way of the flue. A back lining 61 is similarlyformed by notching the same at the corners andproviding horizontalflanges 62, an air space thereby being formed at the back of theoven toserve as insulation and also to act as a flue, flange having an openingtherethrough for the escape of vapors from the space between members 52and through time hole 52. lhe top lining 59 rests on the top flange ofthe rear lining and on the horizontal flange 57 of the oven front 56.The side linings 111 are each formed in one piece and are provided withflanges 111 similar to those, 62,,of back lining described above, Thecentral portion of each side lining of the top oven is provided with arectangular recess, shown at 62', by forming the side linings at thispoint in a channel shape, thereby forming an air space for insulation ofthe side walls. Sheetmetal pieces 63 formed in spaced Uehapes areelectric welded to the flat portions of the side linings, therebyforming passages for air while the U-shapes act as rack supports. In thebroiling or lower oven, holes 63 are pierced to allow air to enter forthe burners. and the U-shapes are continuous allowing a great manypositions for the burner pan which rests thereon.
